Kernrechtsfrage
Whether the taxpayer's share in the inherited building was business or private property for direct federal tax.
Extrahierter Entscheid
The building share remained private property; the taxpayer's office use and prior depreciation bookings did not change that.
Extrahierte Begründung
The property was inherited private wealth, mostly rented to third parties, and only a small part served the taxpayer's business. Under the predominance method, the overall asset stayed in private wealth.
